Randomly popped a p0300 & a p0171 yesterday right after my truck warmed up. Low idle, studders in mid rpm & feels better up high. Steady spark on all 8 coils. I haven't metered anything as I don't have one handy nor a good scan tool.

Brake cleaner spray around the intake did nothing.

Soooo...with random misfires & running lean on the entire bank 1 i'm thinking o2 sensor.

Any other ideas? I'll have my hands on a scanner tomorrow...
